A balanced (self sustaining) ecosystem! Hope this helps!
There are three ways in which exogenous dna can be
introduced into a bacterial genome. These are; transduction, transformation and
conjugation. Transduction is the introduction of exogenous material into bacteria
by viruses; conjugation is exchange of genetic material between bacteria sexual
through reproduction; while transformation
is uptake of exogenous dna by bacteria, from its surrounding, through the
bacterial membrane.
TRANSFORMATION IS THE ONLY THING I CAN THINK OF
Answer:
1. Chemical pollution
2. Nutrient pollution
3. Trash and debris pollution
4. Chemical pollution
Explanation:
- The oil spills create leakages of oil from the carrier directly into the oceans. Which has harmful effects especially for the marine environments.
- It creates a hazard-like situation and badly impacts or affects the productivity of the waters. Hence is chemical pollution as oil had a different chemical composition than water.
- The release of agricultural run-off into the rivers or streams or the nearby areas or urban runoff leads to the problems of nutrients that deplete the oxygen levels from the water and enhances the algae blooms.
- The dumping of plastics and other wastes leads to debris pollution as they dot get easily decomposed and stay for a longer duration in the water. Oil and gasoline again is a chemical pollutant along with motor vehicle exhaust.
Answer:
Electron transport chain
Explanation:
The NADH and FADH2 produced throughout glycolysis and Kreb's cycle are converted into ATP in the electron transport chain with oxygen as the terminal electron acceptor.
The following is a concept map of all NADH and FADH2 produced during cellular respiration.
- In each glycolytic pathway, glyceraldehyde 3-phosphate dehydrogenase produces 1 molecules of NADH as a result of reduction of NAD+.
- Pyruvate dehydrogenase converts pyruvate to Acetyl CoA producing 1 molecule of NADH per pyruvate oxidized.
- In Kreb's cycle, isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, and malate dehydrogenase reactions produce 1 molecule of NADH each. Furthermore, succinate dehydrogenase reaction produces a single molecule of FADH2 per FAD reduced.
- Since, we began with 2 molecules of glyceraldehyde 3-phosphate, we multiply the above figures by 2 and get a total of 10 NADH and 2 FADH2.
